Hello everyone,
I've installed Ubuntu 12.10 i386 (updated) on our school lab room computers. there's a canon printer there that is connected to teacher PC via USB.
I installed it following https://help.ubuntu.com/community/CanonCaptDrv190
the printer worked for just one time well and after a reboot I get this error (Plz click on the below image to enlarge it). The teacher is asking me for "printer"!
